          Abstract

          Este artigo avaliou o uso das boas práticas (alimentação, deambulação, uso de métodos não farmacológicos para alívio da dor e de partograma) e de intervenções obstétricas na assistência ao trabalho de parto e parto de mulheres de risco obstétrico habitual. Foram utilizados dados da pesquisa Nascer no Brasil, estudo de base hospitalar realizada em 2011/2012, com entrevistas de 23.894 mulheres. As boas práticas durante o trabalho de parto ocorreram em menos de 50% das mulheres, sendo menos frequentes nas regiões Norte, Nordeste e Centro-oeste. O uso de ocitocina e amniotomia foi de 40%, sendo maior no setor público e nas mulheres com menor escolaridade. A manobra de Kristeller, episiotomia e litotomia foram utilizada, em 37%, 56% e 92% das mulheres, respectivamente. A cesariana foi menos frequente nas usuárias do setor público, não brancas, com menor escolaridade e multíparas. Para melhorar a saúde de mães e crianças e promover a qualidade de vida, o Sistema Único de Saúde (SUS) e, sobretudo o setor privado, necessitam mudar o modelo de atenção obstétrica promovendo um cuidado baseado em evidências científicas.

          This study evaluated the use of best practices (eating, movement, use of nonpharmacological methods for pain relief and partograph) and obstetric interventions in labor and delivery among low-risk women. Data from the hospital-based survey Birth in Brazil conducted between 2011 and 2012 was used. Best practices during labor occurred in less than 50% of women and prevalence of the use of these practices was lower in the North, Northeast and Central West Regions. The rate of use of oxytocin drips and amniotomy was 40%, and was higher among women admitted to public hospitals and in women with a low level of education. The uterine fundal pressure, episiotomy and lithotomy were used in 37%, 56% and 92% of women, respectively. Caesarean section rates were lower in women using the public health system, nonwhites, women with a low level of education and multiparous women. To improve the health of mothers and newborns and promote quality of life, a change of approach to labor and childbirth that focuses on evidence-based care is required in both the public and private health sectors.

          Se evaluó el uso de buenas prácticas (alimentación, métodos no farmacológicos para el alivio del dolor, caminar y el uso del partograma), además de las intervenciones obstétricas durante el parto, en mujeres con un riesgo obstétrico habitual. Los datos provienen del estudio Nacer en Brasil, una cohorte de base hospitalaria realizada en 2011-2012, con entrevistas a 23.894 mujeres. Las buenas prácticas durante el parto se produjeron en menos de un 50% y fueron menos frecuentes en el Norte, Nordeste y Centro-oeste. El uso de oxitocina y amniotomía fue del 40%, principalmente, en el sector público y en las mujeres de menor nivel educativo. La presión fúndica uterina, episiotomía y litotomía fueron utilizados en: un 37%, 56% y 92% respectivamente. La cesárea fue menos frecuente en mujeres que son usuarias del sector público, no blancas, con menor nivel educativo y multíparas. Para mejorar la salud de las madres y los niños, y con el fin de promover la calidad de vida, el Sistema Único de Salud (SUS), y sobre todo el sector privado, necesitará cambiar el modelo de atención obstétrica mediante la adopción de evidencias científicas.

          Caesarean section without medical indications is associated with an increased risk of adverse short-term maternal outcomes: the 2004-2008 WHO Global Survey on Maternal and Perinatal Health

          Background There is worldwide debate about the appropriateness of caesarean sections performed without medical indications. In this analysis, we aim to further investigate the relationship between caesarean section without medical indication and severe maternal outcomes. Methods This is a multicountry, facility-based survey that used a stratified multistage cluster sampling design to obtain a sample of countries and health institutions worldwide. A total of 24 countries and 373 health facilities participated in this study. Data collection took place during 2004 and 2005 in Africa and the Americas and during 2007 and 2008 in Asia. All women giving birth at the facility during the study period were included and had their medical records reviewed before discharge from the hospital. Univariate and multilevel analysis were performed to study the association between each group's mode of delivery and the severe maternal and perinatal outcome. Results A total of 286,565 deliveries were analysed. The overall caesarean section rate was 25.7% and a total of 1.0 percent of all deliveries were caesarean sections without medical indications, either due to maternal request or in the absence of other recorded indications. Compared to spontaneous vaginal delivery, all other modes of delivery presented an association with the increased risk of death, admission to ICU, blood transfusion and hysterectomy, including antepartum caesarean section without medical indications (Adjusted Odds Ratio (Adj OR), 5.93, 95% Confidence Interval (95% CI), 3.88 to 9.05) and intrapartum caesarean section without medical indications (Adj OR, 14.29, 95% CI, 10.91 to 18.72). In addition, this association is stronger in Africa, compared to Asia and Latin America. Conclusions Caesarean sections were associated with an intrinsic risk of increased severe maternal outcomes. We conclude that caesarean sections should be performed when a clear benefit is anticipated, a benefit that might compensate for the higher costs and additional risks associated with this operation.

            Abnormal placentation: twenty-year analysis.

            This study was undertaken to determine whether the rate of abnormal placentation is increasing in conjunction with the cesarean rate and to evaluate incidence, risk factors, and outcomes. Cases from 1982-2002 were identified by histopathologic or strong clinical criteria. Risk factors were assessed in a matched case-control study, and analyzed using conditional logistic regression models. There were 64,359 deliveries, with cesarean rates increasing from 12.5% (1982) to 23.5% (2002). The overall incidence of placenta accreta was 1 in 533. Significant risk factors for placenta accreta in our final analysis included advancing maternal age (odds ratio [OR] 1.13, 95% CI 1.089-1.194, P < .0001), 2 or more cesarean deliveries (OR 8.6, 95% CI 3.536-21.078, P < .0001), and previa (OR 51.4, 95% CI: 10.646-248.390, P < .0001). The rate of placenta accreta increased in conjunction with cesarean deliveries; the most important risk factors were previous cesarean delivery, previa, and advanced maternal age.

              Maternal and neonatal individual risks and benefits associated with caesarean delivery: multicentre prospective study.

              To assess the risks and benefits associated with caesarean delivery compared with vaginal delivery. Prospective cohort study within the 2005 WHO global survey on maternal and perinatal health. 410 health facilities in 24 areas in eight randomly selected Latin American countries; 123 were randomly selected and 120 participated and provided data 106,546 deliveries reported during the three month study period, with data available for 97,095 (91% coverage). Maternal, fetal, and neonatal morbidity and mortality associated with intrapartum or elective caesarean delivery, adjusted for clinical, demographic, pregnancy, and institutional characteristics. Women undergoing caesarean delivery had an increased risk of severe maternal morbidity compared with women undergoing vaginal delivery (odds ratio 2.0 (95% confidence interval 1.6 to 2.5) for intrapartum caesarean and 2.3 (1.7 to 3.1) for elective caesarean). The risk of antibiotic treatment after delivery for women having either type of caesarean was five times that of women having vaginal deliveries. With cephalic presentation, there was a trend towards a reduced odds ratio for fetal death with elective caesarean, after adjustment for possible confounding variables and gestational age (0.7, 0.4 to 1.0). With breech presentation, caesarean delivery had a large protective effect for fetal death. With cephalic presentation, however, independent of possible confounding variables and gestational age, intrapartum and elective caesarean increased the risk for a stay of seven or more days in neonatal intensive care (2.1 (1.8 to 2.6) and 1.9 (1.6 to 2.3), respectively) and the risk of neonatal mortality up to hospital discharge (1.7 (1.3 to 2.2) and 1.9 (1.5 to 2.6), respectively), which remained higher even after exclusion of all caesarean deliveries for fetal distress. Such increased risk was not seen for breech presentation. Lack of labour was a risk factor for a stay of seven or more days in neonatal intensive care and neonatal mortality up to hospital discharge for babies delivered by elective caesarean delivery, but rupturing of membranes may be protective. Caesarean delivery independently reduces overall risk in breech presentations and risk of intrapartum fetal death in cephalic presentations but increases the risk of severe maternal and neonatal morbidity and mortality in cephalic presentations.
